DESCRIPTION OF EMBODIMENTS

To make the objectives, technical solutions, and advantages of the present disclosure clearer, the following further describes implementations of the present disclosure in detail with reference to the accompanying drawings.

FIG. 1 shows a schematic diagram of an implementation environment according to some embodiments of the present disclosure. The implementation environment may include a terminal 10 and a server 20.

The terminal 10 may be an electronic device such as a personal computer (PC), a mobile phone, a tablet computer, a smart television, or a multimedia playback device. A video player may be installed and run in the terminal 10, to play a video through the video player. The video player may be in the form of a client, or may be in the form of a web page. This is not limited in the embodiments of the present disclosure.

The server 20 is configured to provide a backend service for the video player of the terminal 10. The server 20 may be one server, a server cluster including a plurality of servers, or a cloud computing service center.

The terminal 10 may communicate with the server 20 through a network. The network may be a wired network or a wireless network.

FIG. 2 shows a flowchart of a picture generation method according to some embodiments of the present disclosure. The method is performed by a terminal, and the terminal may be the terminal 10 in the embodiment of FIG. 1. Optionally, the method is performed by the video player (for example, a video client) in the terminal 10. The method may include the following steps:

Step 201: Display a subtitle list of a target video.

The target video may be any video. For example, the target video refers to a video currently displayed by the video player. In the embodiments of the present disclosure, the type of the target video is not limited. For example, the target video may be at least one type of a film, a television series, a variety show, or an animation.

The subtitle list of the target video includes at least one subtitle of the target video. Optionally, the subtitle list of the target video includes all or some subtitles of the target video. Subtitles of a video, as used herein, may include text derived from either a transcript or screenplay of dialogue or commentary in the video. The subtitles are usually displayed at a bottom (or top) of the video when the subtitle function is turned on. The subtitle may be in the same language as the original language spoken or used in the video or may be in another language translated from the original language. The subtitles of the video may each have a timestamp or a display period indicating its corresponding time to appear during the playback progress of the video. This is not limited in the embodiments of the present disclosure. The terminal may display the subtitles of the target video in the form of a list. For example, the list includes several lines, and each line corresponds to one subtitle.

Optionally, the step includes the following several sub-steps:

1. Display a playing interface of the target video.

The playing interface of the target video refers to a user interface playing the target video. For example, as shown in FIG. 3, the terminal displays a playing interface 30 of the target video.

2. Obtain a trigger instruction corresponding to a target operation control in the playing interface.

The target operation control refers to a control used for triggering to perform an image obtaining operation. For example, the target operation control may be a button. Certainly, in other possible implementations, the terminal may be triggered, in at least one manner of a speech, a gesture, or an expression, to execute the image obtaining operation. This is not limited in the embodiments of the present disclosure.

Exemplarily, as shown in FIG. 3, a “subtitle stitching” button 31 is set in the playing interface 30. A user taps the “subtitle stitching” button 31, and accordingly, the terminal obtains a trigger instruction corresponding to the “subtitle stitching” button 31.

3. Obtain a real-time image frame of the target video according to the trigger instruction corresponding to the target operation control.

The real-time image frame refers to an image frame displayed in the playing interface when the trigger instruction is obtained.

In a possible implementation, when the terminal obtains the trigger instruction corresponding to the target operation control, the terminal takes a screenshot of an image frame currently displayed in the playing interface, to obtain a real-time image frame.

In another possible implementation, when the terminal obtains the trigger instruction corresponding to the target operation control, the terminal obtains a currently played timestamp of the target video, and transmits an image obtaining request to a server. The image obtaining request carries identification information of the target video and the timestamp. After receiving the image obtaining request transmitted by the terminal, the server obtains an image frame corresponding to the timestamp as a real-time image frame, and transmits the real-time image frame to the terminal. Accordingly, the terminal receives the real-time image frame transmitted by the server.

In the first manner, the terminal obtains the real-time image frame by taking a screenshot, and latency required for request and response performed between the terminal and the server may be saved, which is timelier and more efficient.

4. Display a subtitle stitching interface.

The subtitle stitching interface includes a subtitle display region and a stitching preview region. The subtitle display region is used for displaying a subtitle, and the stitching preview region is used for displaying an image frame selected by the user.

Exemplarily, with reference to FIG. 3 and FIG. 4, after the user taps the “subtitle stitching” button 31, the terminal displays a subtitle stitching interface 40. The subtitle stitching interface 40 includes a subtitle display region 41 and a stitching preview region 42.

Optionally, the subtitle stitching interface is overlay-displayed on an upper layer of the playing interface in the form of a floating window. A size of the subtitle stitching interface may be preset by a designer, for example, the size of the subtitle stitching interface is 1100×700 pixels.

5. Display the subtitle list of the target video in the subtitle display region, and display the real-time image frame in the stitching preview region.

As shown in FIG. 4, the terminal displays the subtitle list of the target video in the subtitle display region 41. Optionally, each subtitle corresponds to one selection control, and the user may select or deselect the corresponding subtitle through the selection control. In the subtitle display region 41, a selection control 43 corresponding to the subtitle in the real-time image frame is in a checked state, which indicates that the subtitle is selected. In addition, as shown in FIG. 4, a real-time image frame 44 is displayed in the stitching preview region 42.

If there is no subtitle in the real-time image frame, the terminal may display a prompt message in the subtitle display region. The prompt message is used for indicating that there is no subtitle in the real-time image frame. For example, as shown in FIG. 5, when there is no subtitle in the real-time image frame, the terminal displays a prompt message 45 of “no subtitle in the picture currently” in the subtitle display region 41, and a selection control corresponding to the prompt message 45 is in a checked state.

Further, after the real-time image frame is added to the stitching preview region for display, the real-time image frame may become a target image frame, and the subtitle corresponding to the real-time image frame may be a target subtitle. Various operations performed on the target image frame in the stitching preview region may all be applicable to the real-time image frame.

Optionally, in the subtitle list of the target video, the subtitles are arranged from top to bottom in chronological order. A maximum quantity of subtitles that can be displayed in the subtitle display region may be preset by the designer, for example, the maximum quantity is 10. When a total quantity of the subtitles of the target video is greater than the maximum quantity, all subtitles of the target video may be displayed in the subtitle display region in a scrolling to preview manner.

In addition, when the terminal initially displays the subtitle stitching interface, the terminal may display the subtitle in the real-time image frame or the prompt message used for indicating that there is no subtitle in the real-time image frame at a specified position of the subtitle display region. For example, the specified position is the third position in the maximum quantity. Subtitles located before and after the timestamp corresponding to the real-time image frame are respectively displayed above or below the position for the user to select.

Step 202: Obtain, in response to obtaining a selection instruction corresponding to a target subtitle in the subtitle list, a target image frame corresponding to the target subtitle in the target video.

The target subtitle may be any subtitle in the subtitle list. The selection instruction corresponding to the target subtitle refers to an instruction triggered by the user and used for instructing to select the target subtitle. Optionally, as shown in FIG. 6, the user may tap a selection control 46 corresponding to a subtitle “EEEEEEEE” to trigger a selection instruction. Certainly, in other possible implementations, the selection instruction may alternatively be triggered in at least one manner of a speech, a gesture, or an expression. This is not limited in the embodiments of the present disclosure.

The target image frame refers to an image frame within a display period corresponding to the target subtitle. For example, the timestamp of the target image frame in the target video is within the display period of the target subtitle. Optionally, the target image frame is one image frame within the display period corresponding to the target subtitle. Each subtitle in the target video corresponds to one display period, and the display period refers to a period of displaying the subtitle in the process of playing the target video. For example, if a display period corresponding to one subtitle is 15:32-15:36, it indicates that the subtitle is displayed when video content from 15:32 to 15:36 of the target video is played. That is, the subtitle is displayed in all image frames included in the video content from 15:32 to 15:36 of the target video.

In addition, the target image frame may be the first image frame within the display period corresponding to the target subtitle, or may be the last image frame within the display period corresponding to the target subtitle, or may be any image frame within the display period corresponding to the target subtitle. Which image frame within the display period corresponding to the target subtitle is selected as the target image frame may be preset by the designer or the user. This is not limited in the embodiments of the present disclosure.

The terminal may obtain the target image frame corresponding to the target subtitle in the target video in the following manners:

In a possible implementation, the terminal obtains a display period corresponding to the target subtitle, and selects the target image frame from image frames included within the display period.

In another possible implementation, the terminals transmits an image obtaining request to the server, the image obtaining request including identification information of the target video and identification information of the target subtitle. The identification information of the target subtitle may be the display period or a number corresponding to the target subtitle. After receiving the image obtaining request, the server selects, according to the identification information of the target video and the identification information of the target subtitle, image frames within the display period corresponding to the target subtitle from the target video, and then selects the target image frame from the image frames.

For an offline video, the terminal may obtain the target image frame in the first manner, and for an online video, the terminal may obtain the target image frame in the second manner.

Step 203: Display the target image frame in a stitching preview region.

As shown in FIG. 6, after the user selects the subtitle “EEEEEEEE”, the terminal displays an image frame 47 corresponding to the subtitle “EEEEEEEE” in the stitching preview region.

Optionally, an arrangement sequence of the target image frame included in the stitching preview region is consistent with an arrangement sequence of the selected target subtitle in the subtitle list. As shown in FIG. 6, in the subtitle list, a subtitle “AAAAAAAA” is arranged before the subtitle “EEEEEEEE”, and accordingly, in the stitching preview region, an image frame 44 corresponding to the subtitle “AAAAAAAA” is arranged before the image frame 47 corresponding to the subtitle “EEEEEEEE”. In some examples, the arrangement sequence may be chronological.

In addition, display states of the target image frame in the stitching preview region may include the two following states: an unfolded state and a folded state. The unfolded state refers to a display state in which all content of the target image frame is visible (for example, the image frame 44 in FIG. 6 is in the unfolded state), and the folded state refers to a display state in which only a subtitle region in the target image frame is visible (for example, the image frame 47 in FIG. 6 is in the folded state).

The subtitle region refers to a partial region of the target image frame, and the partial region includes the subtitle in the target image frame. Optionally, the subtitle region of the target image frame may be determined according to a position of the subtitle in the target image frame. For example, the terminal may use, according to height information of the subtitle in the target image frame, a rectangular region surrounded by a bottom edge of the target image frame and a top edge of the subtitle as the subtitle region. The height information of the subtitle refers to a distance between the top edge of the subtitle and the bottom edge of the target image frame.

That the terminal adds and displays the target image frame in the stitching preview region may be adding and displaying the target image frame in the stitching preview region in the folded state. That is, no matter the target image frame is arranged before the real-time image frame or after the real-time image frame, the target image frame is added and displayed in the folded state. As shown in FIG. 6, the terminal adds and displays the image frame 47 corresponding to the subtitle “EEEEEEEE” in the folded state in the stitching preview region.

In addition, in the embodiments of the present disclosure, a function of switching the display state of the target image frame in the stitching preview region is further provided. Using an example in which the display state of the target image frame is switched, after the terminal obtains a display state switching instruction corresponding to the target image frame, if the display state of the target image frame is the unfolded state, the terminal switches the target image frame from the unfolded state to the folded state for display; and if the display state of the target image frame is the folded state, the terminal switches the target image frame from the folded state to the unfolded state for display.

The display state switching instruction refers to an operation instruction triggered by the user and used for switching the display state of the image frame. In the embodiments of the present disclosure, the manner for triggering the display state switching instruction is not limited. For example, the instruction may be triggered in at least one manner of an operation control, a speech, a gesture, or an expression. Exemplarily, with reference to FIG. 7 and FIG. 8, in FIG. 7, an image frame 47 corresponding to a subtitle “FFFFFFFF” is in a folded state. As shown in FIG. 8, the user taps an “unfold” button 48 at the lower right corner of the image frame 47, and the terminal switches the image frame 47 from the folded state to an unfolded state for display. In addition, when the image frame 47 is in the unfolded state, if the user taps a “fold” button 49 at the lower right corner of the image frame 47, the terminal switches the image frame 47 from the unfolded state to the folded state for display.

In the embodiments of the present disclosure, collage pictures with different display forms may be generated by switching the display state of the image frame, and the user may adjust the display state of the image frame according to own requirements. In addition, the user may further review picture content in the image frame by unfolding the image frame.

In addition, in response to obtaining a deselection instruction corresponding to the target subtitle, the terminal cancels displaying of the target image frame in the stitching preview region. Optionally, if there is only one subtitle in the subtitle list is in a selected state, the user cannot cancel selection of the subtitle.

Step 204: Generate, in response to obtaining a picture generation instruction, a collage picture according to the target image frame included in the stitching preview region.

The picture generation instruction refers to an instruction triggered by the user and used for instructing the terminal to generate a collage picture. In the embodiments of the present disclosure, the manner for triggering the picture generation instruction is not limited. For example, the instruction may be triggered in a manner such as an operation control, a speech, a gesture, or an expression. After obtaining the picture generation instruction, the terminal keeps respective current display states of the target image frames included in the stitching preview region to generate a collage picture. With reference to FIG. 8 and FIG. 9, after the user taps a “generate collage picture” button 50, the terminal generates a collage picture 51 shown in FIG. 9.

Optionally, when the user taps the “generate collage picture” button 50 to trigger a picture generation instruction, the terminal determines whether a user account is in a logged-in state; if the user account is not in the logged-in state, the terminal displays a login subtitle box that requires the user to perform a login operation of the user account, and generates a collage picture after the user account successfully logs in; and if the user account is in the logged-in state, the terminal directly performs the step of generating a collage picture.

Optionally, in addition to the target image frames included in the stitching preview region, the collage picture further includes related information of the target video. Optionally, as shown in FIG. 9, the related information of the target video includes at least one of the following: a name 52 of the target video, a screenshot timestamp 53 corresponding to the target video, source information 54 of the collage picture, or a two-dimensional code 55 corresponding to the collage picture. The screenshot timestamp 53 corresponding to the target video is a timestamp corresponding to a selected subtitle. For example, the screenshot timestamp may refer to a timestamp of an initial display moment corresponding to the subtitle provided with the earliest display period in selected subtitles. The source information 54 of the collage picture refers to information of a server side generating the collage picture. The two-dimensional code 55 corresponding to the collage picture carries a link address of a shared page of the collage picture and is used for being scanned by the user to obtain the link address, to display the shared page of the collage picture.

Based on the above, in the technical solution provided in the embodiments of the present disclosure, the subtitle list of the target video is displayed, the target image frame corresponding to the target subtitle is displayed in the stitching preview region after the selection instruction corresponding to the target subtitle in the subtitle list is obtained, and then the collage picture is generated according to the target image frame included in the stitching preview region. The solution is simple in operation and time-saving, and can ensure matching degrees between subtitles and video pictures in the collage picture. In the technical solution provided in the embodiments of the present disclosure, screenshot taking and splicing may alternatively be performed on a video playing interface without using third-party software.

In some optional embodiments provided based on the embodiment of FIG. 2, in response to obtaining a complete preview instruction, the terminal performs equal-proportion reduction (i.e., proportional reduction) processing on the target image frame included in the stitching preview region according to a total length of the target image frame included in the stitching preview region and a length of the stitching preview region, to obtain a processed target image frame; and then displays the processed target image frame in the stitching preview region. A total length of the processed target image frame is less than or equal to the length of the stitching preview region. For example, the stitching preview region includes a plurality of target image frames, in response to the complete preview instruction, the terminal scales down the target image frames in the stitching preview region according to a total length of the target image frames and a length of the stitching preview region, to obtain scaled-down target image frames. The terminal then displays the scaled-down target image frames in the stitching preview region.

In the stitching preview region, a transverse width of each target image frame may be a preset value, and a longitudinal length may be determined according to a length-width ratio of the target image frame, to ensure that the length-width ratio of the target image frame in the stitching preview region is consistent with the length-width ratio when the target image frame is played. Since a size of the stitching preview region is limited, when more target image frames are selected by the user and added to the stitching preview region, the target image frames cannot be displayed simultaneously in the stitching preview region, so that the target image frames are displayed in the stitching preview region in a scrolling to preview manner. When the user needs to completely preview all target image frames included in the stitching preview region, the user may trigger a complete preview instruction. For example, the user may trigger the complete preview instruction in at least one manner of an operation control, a speech, a gesture, or an expression. After receiving the complete preview instruction, the terminal performs reduction processing, such as equal-proportion reduction processing, on the target image frames included in the stitching preview region, so that all target image frames included in the stitching preview region can be displayed completely.

Exemplarily, with reference to FIG. 8 and FIG. 10, the subtitle stitching interface further includes an “proportional zoom” button 56. The user taps the “proportional zoom” button 56 to trigger the complete preview instruction. As shown in FIG. 10, the terminal reduces the total length of the target image frames included in the stitching preview region to be consistent with the length of the stitching preview region, and performs equal-proportion reduction on the width, so that the user can view an overall arrangement layout of all selected target image frames in the stitching preview region.

In addition, after displaying the processed target image frames in the stitching preview region, in response to obtaining an instruction of exiting the complete preview instruction, the terminal restores the processed target image frames in the stitching preview region to patterns before the processing for display. With reference to FIG. 8 and FIG. 10, the subtitle stitching interface further includes an “original size” button 57. The user taps the “original size” button 57 to trigger the instruction of exiting the complete preview, and the terminal restores the image frames in the stitching preview region from patterns in FIG. 10 to patterns in FIG. 8 for display.

Based on the above, in the technical solution provided in the embodiments of the present disclosure, a function of completely previewing the target image frames in the stitching preview region is provided, so that the user can view the overall arrangement layout of all selected target image frames in the stitching preview region, thereby better meeting the user requirement.

In some other optional embodiments based on the embodiment of FIG. 2 or provided by the foregoing optional embodiments, functions of saving and sharing the collage picture are further provided.

With reference to FIG. 8 and FIG. 11, the user taps the “generate collage picture” button 50 to trigger a picture generation instruction, and the terminal generates a collage picture 51 and displays the collage picture 51 in the stitching preview region. After the collage picture 51 is generated, an operation control used for implementing at least one function of saving, sharing, or re-editing appears in the subtitle stitching interface. As shown in FIG. 11, the subtitle stitching interface includes a “download to local” button 58, a “re-edit” button 59, and related buttons for sharing the collage picture to Weibo or other social application platforms.

The user taps the “download to local” button 58 to trigger a save instruction, and the terminal displays a subtitle box for the user to select a save position. The user selects the save position according to own requirement, and the terminal saves the collage picture to a corresponding position.

The user taps the “re-edit” button 59 to trigger a re-editing instruction, the terminal returns to the subtitle stitching interface shown in FIG. 8, and the user may reselect the target subtitle or adjust the display state of the target image frame according to own requirement.

The user taps a share button corresponding to a target platform to trigger a share instruction, and the terminal transmits the collage picture to other users in the target platform according to the user requirement.

As shown in FIG. 12, when a shared user receives the collage picture or a shared link transmitted by the sharer on a terminal such as a mobile phone (or other mobile devices), the shared user may open a web page 120 of the mobile terminal by scanning the two-dimensional code of the collage picture or tapping the shared link on the mobile phone. The shared user may watch the target video by tapping a control used for watching a video on the web page 120 of the mobile terminal, such as a “video watching” button 121. Optionally, the shared user needs to open a client or a web page corresponding to an XX video when watching the target video. If the client corresponding to the XX video is installed in the mobile phone of the shared user, after the shared user taps the “video watching” button 121, the mobile phone automatically opens the client corresponding to the XX video for the user to watch the target video; and if the client corresponding to the XX video is not installed in the mobile phone of the shared user, after the shared user taps the “video watching” button 121, the mobile phone jumps to the web page corresponding to the XX video for the shared user to watch the target video.

As shown in FIG. 13, when the shared user receives the collage picture or the shared link transmitted by the sharer on a PC, the shared user opens a web page 130 of the PC terminal. The shared user may watch the target video by tapping a “video watching” button 131. Optionally, the shared user needs to open a client or a web page corresponding to an XX video when watching the target video. If the client corresponding to the XX video is installed in the PC of the shared user, after the shared user taps the “video watching” button 131, the PC automatically opens the client corresponding to the XX video for the user to watch the target video; and if the client corresponding to the XX video is not installed in the PC of the shared user, after the shared user taps the “video watching” button 131, the PC jumps to the web page corresponding to the XX video for the shared user to watch the target video. In addition, the web page 130 may further include a “make subtitle collage picture” button 132, and after tapping the “make subtitle collage picture” button 132, the shared user may also make a subtitle collage picture in the manner described above.

FIG. 14 shows a flowchart of a picture generation method according to some other embodiments of the present disclosure. The method is performed by an interaction between a terminal and a server, the terminal may be the terminal 10 in the embodiment of FIG. 1, and the server may be the server 20 in the embodiment of FIG. 1. The method may include the following steps:

Step 1401: A terminal displays a subtitle list of a target video.

Step 1402: In response to obtaining a selection instruction corresponding to a target subtitle in the subtitle list, the terminal generates an image obtaining request.

FIG. 16 shows a schematic flowchart of a server side after the server receives a subtitle obtaining request transmitted by a terminal, and the server may be the server 20 in the embodiment of FIG. 1.

Step 1601: A server receives a subtitle obtaining request transmitted by a terminal, where the subtitle obtaining request is used for requesting to obtain a subtitle list of a target video, and the subtitle obtaining request may carry identification information of the target video.

Step 1602: The server determines whether the subtitle list exists in the target video, if yes, step 1603 is performed; otherwise, step 1606 is performed.

Step 1603: The server obtains height information of a subtitle of the target video, where the height information of the subtitle is used for indicating a position of the subtitle in an image frame, so as to ensure that the subtitle is visible to a user when the terminal displays the image frame in a folded state. Optionally, the server searches a database for the height information of the subtitle of the target video.

Step 1604: The server obtains the subtitle list of the target video and a display period corresponding to each subtitle. Optionally, the server invokes an interface provided by a storage server configured to store subtitle information, to obtain the subtitle list of the target video and the display period corresponding to each subtitle from the storage server, where the display period may be represented by using a timestamp when the displaying of the subtitle is started and a timestamp when the displaying of the subtitle is ended.

Step 1605: The server transmits the subtitle information of the target video to the terminal, the subtitle information including the subtitle list of the target video, the display period corresponding to each subtitle, and the height information of the subtitle.

Step 1704: The server transmits the target image frame corresponding to the target subtitle to the terminal.

Step 1705: The server transmits an authentication failure response to the terminal.

It is to be understood that, the steps of the embodiments of the present disclosure are not necessarily performed according to a sequence indicated by step numbers. Unless explicitly specified in this specification, the sequence for performing the steps is not strictly limited, and the steps may be performed in other sequences. In addition, at least some of the steps in the embodiments may include a plurality of sub-steps or a plurality of stages. These sub-steps or stages are not necessarily performed at the same moment, but may be performed at different moments. These sub-steps or stages are not necessarily performed sequentially, but may be performed by turns or alternately with other steps or at least some sub-steps or stages of other steps.

An application program used for implementing product functions of the terminal side of the present disclosure may adopt a model view controller (MVC) architecture, including the following three layers: a presentation layer, a control layer, and a data layer.

The presentation layer is a user interface (UI) presentation framework. FIG. 18 shows a UI presentation framework corresponding to a subtitle stitching interface 180, and the UI presentation framework may include the following three parts: a subtitle region 181, a picture region 182, and a sharing region 183.

Optionally, the subtitle region includes a subtitle list, and the subtitle list includes several content frameworks. As shown in FIG. 19, each content framework 190 includes a selection control 191 and a subtitle text 192.

A quantity of content frameworks included in the subtitle list is determined according to a quantity of subtitles included in the target video. The user may select or deselect a corresponding subtitle by tapping the selection control in the subtitle list. After the user selects a target subtitle, a target image frame corresponding to the target subtitle is added to and displayed in the picture region.

In addition, the subtitle region may further include the following two elements: a prompt box and a return control. As shown in FIG. 20, when a quantity of selected subtitles in the subtitle list exceeds a quantity set by a program, the prompt box 200 is displayed in the subtitle region. In addition, the return control 210 may be further displayed at the lower right corner of the subtitle region, for triggering to return to the top of the selected subtitles.

As shown in FIG. 21, the picture region 182 may include: a stitching preview region 182 a, an “original size” button 182 b, an “proportional zoom” button 182 c, and a vertical scroll bar 182 d. The stitching preview region 182 a displays a content framework list formed by overlaying a plurality of picture controls. When the height of the content framework list is less than the height of the stitching preview region 182 a, the vertical scroll bar 182 d is automatically hidden; otherwise, the vertical scroll bar 182 d may appear and provide a scroll operation to locate the content framework list to a corresponding position.

The “original size” button 182 b and the “proportional zoom” button 182 c provide a function of previewing a combination effect of current picture layers for the user. When excessive pictures are selected by the user, leading to that the longitudinal length of the content framework list exceeds the longitudinal length of the stitching preview region 182 a, the vertical scroll bar 182 d needs to be used to scroll to preview, which is difficult for the user to intuitively feel an overall splicing effect. After the “original size” button 182 b and the “proportional zoom” button 182 c are provided, when the user taps the “proportional zoom” button 182 c, the terminal reduces the overall content framework list until the length is equal to the length of the stitching preview region 182 a; and after the user taps the “original size” button 182 b, the content framework list restores to the effect before the “proportional zoom” button 182 c is tapped.

Each time when a target subtitle is added to or deleted from the subtitle list, the terminal notifies the picture region, and the picture region simplifies the operation as: performing an operation of newly adding a picture layer or deleting a picture layer for an n^(th) selected target subtitle in the subtitle list. When a picture layer is newly added, a content framework container is newly built to display a corresponding target image frame, and whether an initial display state is an unfolded state is determined, where a real-time image frame is generally in an unfolded state by default. After the picture layer is newly built, the newly built picture layer is inserted into the existing content framework list according to a sequence of a subtitle option corresponding to the picture layer, and a presentation sequence of the image frame herein is consistent with a sequence of the subtitle in the subtitle list.

The sharing region is used for saving or sharing the generated collage picture. Optionally, the sharing region includes a “download to local” button, a “re-edit” button, and a row of shareable icon lists. Icon buttons on the shareable icon list correspond to sharing platforms.

The data layer is mainly responsible for storing data, such as identification information of a target video, a subtitle list of the target video, height information of a subtitle, a display period corresponding to each subtitle, and a target image frame. The subtitle list of the target video is provided by the server for the terminal. When the data layer performs processing on the target video, a screenshot timestamp corresponding the target video needs to be located, so as to locate the screenshot timestamp corresponding to the target video when the UI layer displays the target video. After data is requested and processed completely, the data is encapsulated into structural information, and the structural information is transmitted to the control layer.

The control layer may use CDialogueEditMgr as a control class, including a data class IDialogueInfoDetail and an interface class CDialogueEditWindow. The CDialogueEditMar used as the control class functions as a bridge between the data class and a presentation class, to combine functions of the two classes, and encapsulate the functions into a class for an outer call. In this way, logic and interfaces are well separated, and the control class obtains data from the data class and transmits the data to the presentation class for interface presentation.

When the terminal starts to share the subtitle, the control layer is responsible for creating a function window and starts a data request, after the data request is completed, a notification is returned to the control layer, and the control layer is then responsible for transmitting the data to the UI layer and instructs the UI layer to draw interface information. Screenshot response of a kernel of a local player also instructs, through the control layer, the UI layer to display a real-time image frame corresponding to the target video.
